Welcome to Pradopoint

Check the fan belts, mine will do the same thing on a cold morning if the belts are a bit loose - clicking that is from the belts hitting each other.

A couple of things....
Glow plugs are still active at this time - it may be alternator load of some kind
There was something about the injection pump & a pin & spring that could tap under certain circumstances....sorry I can't remember further details.
Your timing belt/tensioner may be due. Early models it was due @ 100,000km newer ones @ 150,000km.

Can you pinpoint the general area of the noise?

Cheers
